The dev package can be accidentally uninstalled and sys
admins who are unaware of this can land up in trouble if
they uninstall this package by mistake. This may not be a
bug but I have seen cases of people who have actually done
this and had severe problems once they did this. This is
because according to RPM no package needs dev (this is
obviously very wrong).
# rpm -q --whatrequires dev
no package requires dev
